DISK ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 781,735, dated February'7, 1905.

Application filed August 3,1904. Serial No. 219,363.

Be it known that l, Winnmn A. )loGmn- ERY, a citizen of the UnitedStates, residing at Maytlower, in the county of Clay and State of Northarolina, have invented a new and useful Disk Attachment, of which thefollowing is a specification.

This invention relates to disk attachments for plows, cultivator-s, andthe lilte: and it has for its object to provide a device of this classwhich shall possess superior advantages in point of simplicity,durability. and general ctliciency.

\Yith these and other ends in view, which will readily appear as thenature of the invention better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claims.

in the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being, however, understood thatno limitation is necessarily made to the precise structural detailstherein exhibited, but that changes and modifications may be made withinthe scope of the inven tion without departing from the spirit orsacrificing the etticiency ot' the same.

In said drawings, Figure 1 is a side elevation of a doublecultivating-plow, showing the attachment applied thereto. Fig. 2 is aperspective view showing the attachment separated from the plow. Fig. 3is a sectional view taken on the line 3 3 in Fig. 1. Fig. 4 is aperspective detail view showing a portion of the hub with one of itsflanges, the adjacent end of a brace, and the intermediate adjustingwedge.

attachment seen from the inner side. Fig. (5

Fig. :3 is a side elevation of the equipped with a spading-dislt and aspecial 3 brace used in connection with the latter.

I is a detail view illustrating a. modification.

Correspomling parts in the several ligures are indicated by similarnumerals t reference.

The improved attaclnnent includesa hub 1, provided withradially-extending flanges 2 These flanges are for convenient connectionFig. i

with braces T and 5, each of which is connected with its respectiveflange by means of a pivotal bolt 6, extending through the brace andflange and also through an interposed wedge-shaped l)l0(:l{ T, which maybe so adjusted as to cause the braces to be held at various angles withrelation to the tlanges and consequently to the hub l. The brace isprovided at the end thereof with a boxing 8, which hingedly engages aclip 9, by means of which it is connected with the beam of an ordinaryplow, as illustrated in Fig. 1 of the drawings. The brace & is providedwith a slot 11, engaging the head of a hook-bolt 12', whereby it islikewise connected with the plow-beam 10. It will be seen that theslotted brace t is capable of adjustment with relation to the plow-beam,said adjustment being etl'ected by means of a lever 12, t'ulcrumed at T3and having a springactuated dog H engaging a cam-segment 15, wherebysaid lever and its related parts may be retained at any desired point ofadjustment. The tree end of the lever 12 is connected pivotally with oneof a plurality of perforations 16 by a linlt 0r hanger 17, the lower endof which is pivotally connected with the llange ot the hub.

The hub or bushing 1 serves to support a disk 18, which may be of anydesired construction. In Fig. 1 an ordinary solid concave-convex dislthas been shown. In Fig. (i has been illustrated a spading-dislt,(specially designated 19,)and it is to be understood that a dislt of anysuitable well-known construction may be used in connection with thisdevice. lVhen a spading-dislt is shown, as in Fig. 6 of the drawings, lprefer to substitute for the brace 5 a special brace 20, having ashouldered end .21, as shown.

ln Fig. T of the drawings has been illustrated a modilied form of theinvention whereby provision is made for the lateral adjustment ot' thedislt instead of the vertical adjustment, which is etl'ected through themedium ot' the brace LT and adjusting-lever 12 in the constructionalreadydescribed. Under this modification the brace connected with therearwardly-extelnling l'lange 2 of the hub, which brace in this ligureis designated t", is l bent to form an arc, the upper end of which,

which is provided with a slot 11", is adapted to rest upon theleft-handbeam of a double plow, with which it is connected adj ustably by meansof a hook-bolt 12*. It is obvious that this construction enables lateraladjustment of the hub carrying the disk to be efiected in a simple andconvenient manner.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.\Yhen a solid disk is used, it may be adjusted at any desired angle withrelation to the growing plants, so as to throw the loose dirt over theroots of the plants in advance of the plows, thus protecting the plantsand enabling the weeding operation to be performed without injury to theplants. Whenever desired. a spading-disk or a disk of any other suitablespecial construction may be substituted for the solid disk, and thedevice is thus capable of a varietyof uses, which will be readilyunderstood 5 and appreciated.

Having thus described the invention, what is claimed is 1. In a diskattachment, a hub having rad iallyextending flanges, braces connectedwith said flanges, pivotal bolts constituting the connecting means, andwedges mounted upon said pivotal bolts between the braces and theflanges.

2. In a device of the class described, a hub having rad ially-extendingflanges, braces connected with said flanges, a plow-beam, means forconnecting the forward brace to said plowbeam, a hook-bolt engaging thelatter and extending through a slot in the rearward brace, a linkconnected pivotally with one of the flanges of the hub, and anadjusting-lever pivotally connected with said link.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
